FEED ATTACHMENT FOR PRlNTlNG-PRESSES.

SPECIFICATION formingpart of Letters Patent No. 667,765, dated February12, 1901.

Application filed December 9, 1899. berial No. 739,822. (No model To allwhom, it may concern.-

Be it known that I, THOMAS L. CANNON, a citizen of the United States,residing at Belmond, in the county of Wright and State of Iowa, haveinvented a new and useful Feed Attachment for Printing-Presses, of whichthe following is a specification.

My invention relates to printing-presses, and particularly to that classknown as oscillating or job presses, in which the printing is done onsheets or cards fed in by hand, the object being to provide an improvedattachment for such presses whereby they are rendered automatic as tofeeding, the printing being done upon a continuous strip or web of paperand the proper lengths cut off after each impression.

With this object in view the invention consists in the improvedconstruction and novel combinations and arrangements of partshereinafter fully described and afterward specifically pointed out inthe claims.

In the drawings forming part of this specification, Figure 1 is aperspective view of part of a printing-press having myimprovedattachment for feeding and cutting mounted thereon. Fig. 2 is a view inelevation of the paper-clamp with one side of the tube broken away. Fig.3 is a detail sectional view on the dotted line 3 3 of Fig. 2. Fig. 4:is a view showing the tracks in section and the carrier and movablegripper in elevation, parts of the carrier being broken away. Fig. 5 isa view showing the tracks in section and the carrier and knives inelevation. Fig. 6 is a longitudinal sectional view on a plane cuttingthrough the carrier, movable gripper, knife, and bill-box, the inner endof the track being broken away. Fig. 6 is a detail perspective view ofpart of the track and of the cam-latch for operating the gripper. Fig. 7is a detail view, in side elevation, showing other means for operatingthe knife. Fig. 8 is a detail View similar to Fig. 4, showing means foroperating and guiding the movable gripper, the gripper being shownclosed. Fig. 9 is a similar view with the gripper closed. Fig. 10 is adetail view, partly in section, showing the perferred means for joiningthe shafts of the paper-clamp. Fig. 11 is a detail perspective view ofthe paper-roller and box, partly broken away.

Like numerals of reference indicate the same parts wherever they appearin the several figures of the drawings.

Referring to the drawings by numerals, 1 indicates the bed of anordinary job or oscillating press, pivoted at its lower end, as usual,(not shown,) and carrying the form 2. The frame is indicated at 1 andthe platen at 5, while 6 6 indicate the large gear-wheels,which carrycrank-pins 7, upon which are mounted the outer ends of rods or pitmen 8,connected at their opposite ends upon pins 9, projecting from the sidesof the bed. These parts are all of any usual or Well-known construction,and the oscillating movement of the bed is caused by the construction ofthe described parts in the usual manner.

10 indicates the usual supporting-frame for the press-table, upon theedges of which a lug is engaged, said lugs depending from therectangular frame of my attachment, said frame being composed of sidebars or tracks 12 13 and end bars 14 15, the attachment being therebysecured to the table-frame of the press in place ofthe table previouslyremoved.

16 indicates a box or case mounted on a shaft 17, journaled in sidesupports 18 19 and provided with a crank-handle 1 9. Said shaft supportsthe roll of paper between disks 20 21, threaded on the shaft andsimultaneously adjusted toward or from each other by turning the shaft,whereby wider or narrower webrolls are centered on the shaft. The web 22passes out of the case at an opening 23, up over the platen 5, and overmy attachment, passing first under the paper-clamp 24. This paper-clampconsists of rubber rings or tires mounted on metal rings 25, threaded onright and left hand threaded shafts 26 27, journaled in line with eachother in lugs 28 29, rising from tracks 12 13, said shafts being coveredby a tube 30, slotted at 31 to permit of connection between the rubberrings outside the tube and the metal rings inside the tube, the meetingof the shafts being secured together, as in Fig. 2, or preferably as inFig. 10, by dovetailing one end in the other and slipping split thimble32 over said ends. When the paper is pulled forward under the rubberrings, it passes freely, the rings and tube turning; but all backwardmovement is prevented by means of a pawl 33, which engages the teeth ofa ratchet-wheel 34., rigidly secured on shaft 27 and as shown in Figs. 1and 2. The cranks 29 are provided on the paperclamp for the purpose ofconveniently rotat ing the same when the paper is first placed inengagement therewith, so that the paper can be fed to position to beengaged by the gripper of the carrier, to be hereinafter described, atthe beginning of the printing.

On the inner faces of tracks 12 and 13 are provided either ribs 35, asin Figs. 1, 4, 5, and 6, or grooves 36, as in Figs. 8 and 9, upon or inwhich the edges of a plate or carrier 37' are mounted, so as to permitof the free sliding of the carrier on the tracks, such movement beingfurther facilitated, if desired, by means of ball-bearings 38. Figs. 4and 5.

39 39 indicate levers pivoted on pins 40, projecting from lugs 11, saidlevers being recessed at their lower ends to surround the pins 40 andprovided with holes 41 in their upper ends to receive pins 42, whichconnect them with links or bars 43,pivotally connected to lugs 44.,projecting upwardly from the carrier 37 at its sides. The carrier 37 isrecessed at 45, as shown in Figs. 4, 5, 8, and 9, and in said recessesare pivotally mounted parallel links 6L6, which at their outer ends arepivotally connected to and support a gripper-bar 47, provided with teethon its under face.

48 indicates'a groove in track 12, in which the end 49 of gripper-bar 47travels during its outward movement, and 50 a similar groove in track13, in which the end 51 of the gripper-bar travels duringits in wardmovement. Inasmuch as the gripper-baris raised during its returnmovement, the groove 50 is in a higher horizontal plane than groove 48,and when either end of the gripper-bar is in its respective groove theopposite end slides on the opposite track, so that the gripper-bar isprevented from moving laterally of the carrier, and consequently, owingto its being mounted on the parallel pivoted links, is also preventedfrom moving vertically, the two positions being clearly illustrated inFigs. 8 and 9. At the outer end of the groove 48 track 12 is cut away,forming a recess 52, in which is located a cam latch or switch 53,secured to the track, and provided with ahead with a downwardly-inclined outer end 54 and a laterally-inclined innerend 55. Whenend 49 reaches cam latch or switch at the end of the forward movement,it rides under outer end 54 of the switch and the switch yields upwarduntil said end passes the head, when it springs down to its normalposition. Upon the beginning of the inward movement the gripper-barrides out laterally on the inclined inner end 55, by which it is movedendwise, and consequently raised, the end 51 being forced into groove 50in track 13, in which it remains until the end of the inward movement,the gripper-bar being thus held raised, as in Fig. 9. At the end of theinward movement end'5l strikes a wedge-shaped block 56, by which it ismoved endwise and forced out of groove 50 and into groove 48, ready forthe outward movement. During the outward movement the gripper 47 carriesthe paper with it, and during the inward movement it travels over thepaper to again clamp it for the next outward movement. The extent ofeach movement is regulated by adjusting the attachment of levers 39 andlinks 43.

' 57 indicates a knife pivoted at 58 to the carrier and normally heldraised, as in Fig. 5, by a spring 59. The free end 60 of the knifeprojects over track 13 and at the end of the outward movement of thecarrier rides under an inclined bracket 61 on the track, forcing itdownward, its edge coacting with a cutting edge 62, formed on or securedto the carrier, and severing a printed length of the web, which dropsinto a box 63, arranged to receive it, the box and the whole attachmentbeing supported by legs 64. This method of operating the knife isclearly illustrated in Fig. 1; but it may also be forced downward by theouter ends of levers 39, as shown in Fig. 7, in which case the inclinedbracket 61 is dispensed with. By means of this attachment any ordinaryjob-press may be quickly converted into a web-printing press. The webwill be printed, fed forward, and cut of]? in proper lengths in themanner described, thus avoiding the necessity of hand-feeding andpermitting of much more rapid and accurate work.

It will be readily understood by those skilled in the art that manyslight changes might be made in the details of construction withoutdeparting from the spirit and scope of my in vention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is
